Abstract : Many naval and scientific requirements exist for a highly directive acoustic antenna capable of scanning an underwater area. To date no attempt has been made to exploit the many advantages possible in the use of thin, non-spherical lens antennas for acoustic scanning. Based on the success of an approximation design technique for radar lenses and the suitability of 3120 RTV, a rubber encapsulating compound, for acoustic lens construction, this investigation was initiated to study the possible application of radar lens design techniques to an acoustic lens.
